Butterfly bushes are carefree deciduous shrubs that are reliably fragrant and easy to grow. Butterflies swarm to their blooms all summer long. 'Lochinch' has extremely fragrant lilac-blue flowers with orange eyes. It is a cross between B. davidii and B. fallowiana. Its arching, mounded habit typically reaches 3 to 5 feet in one season, but can grow much taller in the deep South. The 8-  to 12-inch-long flower spikes begin in late summer and bloom until frost, starting a little later than the B. davidii cultivars.

Butterfly bushes are carefree deciduous shrubs that are reliably fragrant and easy to grow. Butterflies swarm to their blooms all summer long. 'Black Knight' has deep purple-blue, almost black, flowers in elongated clusters on arching branches to 10 feet tall if not cut back, and half that size if cut back. The blooms come from early summer to first frost. The foliage is willow-like and grayish green.

This fragrant, blue-flowered species is more vigorous and heat tolerant than the blue cultivars. It blooms from late spring to early summer, and its foliage persists throughout the season with adequate moisture.

English lavender has silvery gray, aromatic foliage topped in summer with lavender-blue to dark purple flowers on long stems.

These double-flowered grape hyacinths are a good candidate for beds and borders because they increase only by division. They also bloom longer than those that hasten through spring eager to set seed. April-flowering 'Blue Spike' has the largest inflorescence of the species, with fully double flax-blue fluffy heads (each pedicel carries multiple individual flowers instead of one) and narrow, linear leaves.

These double-flowered grape hyacinths are a good candidate for beds and borders because they increase only by division. They also bloom longer than those that hasten through spring eager to set seed. 'Fantasy Creation', a sport of 'Blue Spike', has a large pyramidal raceme resembling broccoli. Its blue flowers gradually turn purple, then green, fading toward yellow. It doesn't wilt and rarely sets seed, making it useful for dried flower arrangements.

Grape hyacinths are hardy, easy to grow, and have long-lasting blooms--no garden should be without them. 'Saffier' is a good candidate for beds and borders because it increases only by division. Its strong, rigid flower stalks start celery-green and mature to robust medium-blue blossoms with distinct pale-green lips at the mouth of each floret. The constricted openings prevent access to pollinating insects, resulting in blooms that last a full month and making them excellent cut flowers.

This drought-tolerant perennial bears abundant pure blue flower spikes in early summer and until fall if spent flowers are removed promptly. It forms an erect clump 20 inches tall by 18 inches wide, with wrinkled, softly hairy leaves.

This short-lived perennial from the Himalayas has scented, hairy leaves and forms a small shrub 2 feet tall by 2 feet wide. It bears 1.5-inch-long purplish-blue flowers with white lips (called bee lines) from early to late summer. The flowers are clasped by rusty colored calyxes that accent color of the blooms. Salvias are some of the showiest plants for containers, annual borders, and mixed borders. Butterflies and hummingbirds love them.
